Dear Andrew Myers, this method looks interesting, as it is proportional, Condorcet and non STV-like. You write on your web-page, that: the correctness of the algorithm depends on a currently unproved conjecture: that if improvement of a committee is possible, it can be done by replacing one

Dear all, A mathematically more sound notation of the importance of the functions of the council members would be the following: M1M2=M3M4=M5=M6=M7, where Mn is a member of the set of all council members. instead of P[VPa, VPb][Ma, Mb, Mc, Md]. The unified method is called Schulze generalized

Dear all If we study Condorcet voting with the two types of ballots: ranked and hybrid, then the differences can be drastic: Normal ranked ballots: 30 BCA 30 ACB 1 C (i.e. CA=B, when using Schulze, see http://en.wikipedia.org/wiki/Schulze_method#Ballot) 1 CBA Pairwise preferences A B C A 30 30

Dear Peter Zbornik, you wrote (9 May 2010): In your paper schulze3.pdf, there are some instances, where the Schulze proportional ranking fails to produce an unambiguous ordering (see for instance the result for data set A10). Why do there ambiguities occur and how would you recommend them

Dear all, an alternative way to count wins against equally ranked candidates, would be to give both 0.5 wins per vote and not 0 as I did in my previous mail. Thus the current state: AB gives 1:0. A=B gives ?:? (A=B is only allowed at the end of the ballot) The proposal above: AB gives 2:0. A=B

Hi Peter,   We consider rank ballots that allow equality of ranking and truncation all the time. For Condorcet methods the question of how to treat equality of ranking is what Juho and I usually talk about. If Markus prefers not to use the split vote treatment it is probably because it violates
